100mg CBD/100mg THC Verano’s Avexia Epsom Salt Soak and Pain Relief Balm both contain Tetrahydrocannabinol (THC) which is the most abundant compound and occurs naturally in the cannabis plant. When combined with all natural elements and oils in a topical formulation, it’s a great method of relief, adding a therapeutic touch to a relaxing soak in the bath or a soothing massage after a long day of work.
